May I make a suggestion? When huge tasks feel too overwhelming to even get started, try breaking them down into small bite size pieces. Set a reminder on your cell phone for a time that works well in your schedule, not late when you're tired, or early morning when you need to get ready for work. List the task you'd like to attack in your reminder such as "Organize Bathroom Countertop."
Take a "before" picture. Then set a timer for only 10 mins. Devote only 10 mins to that task.
Do whatever you can in that timeframe with upbeat music. Something that makes you want to move, or at least tap your feet or sing along with. It will probably be about 3 songs.
When the time is up, take an "after" picture, forgive yourself for what didn't get done and reset your reminder for the same time next week. Eventually it will all get done.
